To @ZZ whom t may concern:

Be it known that we, HENRY E. NIEsE and GEORGE DINKEL, of Jersey City, New J ersey,l have invented a certain Improvement in Ap- 5 paratus for Cooling Sugar, of which the folf lowing is a specification.

Our invention is especially designed to effect the expeditious cooling of soft sugar immediately after its discharge from the centrif- 1o ugal machines in which it is drained. To that end we provide a suitable arrangement of conveying devices, by means of `which the sugar received from the centrifugal machines is conducted to and discharged upon a scattering I5 wheel arranged within a suitable chamber, from which the sugar falls by its own gravity through a pipe, into the lower part of which there is introduced from an adjustable nozzle a strong blast of cold air, which performs the 2o double function of driving the falling sugar onward with accelerated velocity and of cooling the sugar, with the particles of which it is thus brought into contact. To facilitate the distribution of the sugar thus cooled, it isl clined chute, by the manipulation of which the stream of cooled sugar may be given the various directions required to enable it to be thrown into different bins or receptacles. 3o rlhe accompanying drawings of apparatus illustrating our inventions are as follows:

Figure l is a vertical section of portions of several floors of a building containing our apparatus, so arranged that the sugar discharged is carried up to a higher floor, and thence permitted to fall until it reaches the bins in which it is deposited after it is cooled. Fig. 2 is a top view of a twin screw-conveyer bymeans elevator. Fig. Sis asection upon an enlarged scale of a swiveling pipe, nozzle, and chute into which the sugar falls from the pipe lead-` ing from the chamber into which it is deliv- Fig. 4 is a top view,

showing the bottoms ofthe receiving-bins and the twin screw-conveyers by which the sugar` in them is forced toward the discharge-hole,

` through which it falls upon the usual crushingrollers. t 5o In the structures exhibited in the drawings a row of centrifugal machines, A A, is arranged over the row of chutes c, which discharge the sugar from the centrifugal machines upon the endless belt B, by which the sugar is carried horizontally forward and dropped into the trough C, in the bottom of which there is arranged a horizontal conveyer composed of twin screws D and d, which rotate in opposite directions, and which are respectively pro- 6o vided with right-hand and left-hand screwblades. The stems of these screws extend outl side the end C of the trough, and are pro vided, respectively, with the gears D d', which mesh into each other. screws D and cl is transmitted from a suitably placed'shaft to the pulley G2. By the operation of these screws the sugar is pushed into the inclined pipe E, by which it is conducted 'to the bottom of the case F of the belt-eleva- 7o i tor G. By the use of the twin screws rotating in opposite directions, having their opposed peripheries moving upward, the sugar in the trough C is prevented from arching, and by properly regulating the speed of rotation of the twin screws the quantity of sugar delivered to the elevator is graduated with reference to the capacity of the elevator to carry it upward from the bottom of the case F.

If desired, there may be arranged within 8o the pipeE the pair of crushing-rolls e, driven by power transmitted from the shafting in any convenient manner.

The beltelevator G is provided with suitably-formed buckets, in which the sugar is car- 8 5 ried upward from the bottom of the case F to the top, where it is discharged into the inclined pipe H, from the lower end of which it falls upon a scattering-wheel, I, which is rotated with sufficient velocity to scatter the 9o y sugar falling upon it in thechamber J. The chamber Jis the tunnel-shaped mouth of the inclined pipe K, downwhich the sugar falls by its own gravity, and from the lower endof which it is discharged into the swiveling tube L, the lower end of which is bent to an angle Power to rotate the 65 posited in the upper end of the chute M. A

powerful blast of cold air is conducted to and dischargedin a downward direction into the inclined lower end of the tube Lby the gooseneck pipe N, the lower end of which loosely surrounds the upper end of the air-service pipe O, and is provided with a bearing upon the table N. The lower end of the goose-neck N is in vertical alignment with the upper part of the tube L. The chute M is supported by the braces M and M2, which are afxed to the collar M, surrounding the lower end of the goose-neck. and chute M and the goose-neck N have a common vertical axis of rotation. The coldair blast is supplied to the air-service pipe O by means of a suitable blower, O.

The drawings represent four receivingbins, P P P2 P3, adjoining each other, with the swiveling goose-neck and chute so arranged above them as to permit the sugar to be dis-y charged into either one by turning the gooseneck and chute upon their vertical axis. In the drawings the vertical section of the receiving-bins is taken through the line x a" in Fig. 4, and thus shows in elevation the two twin screw-conveyers Q and Q, which are employed to force the sugar fromv the bins P2 and P3 to the discharge-opening R. Similar twin screw-conveyers are provided for the same purpose at the bottoms of the bins P and P. A portion, S, of each of the outer sides of the bins P P P2 P3 is inwardly and downwardly inclined, as shown.

A pair of crushing-rollers, T, may, if -de- By this construction the tube L` sired, be arranged in the usual manner immediately beneath the discharge-opening R, for the purpose of crushing the sugar discharged from the receiving-bins.

Ve claim as our inventionl. The herein-described apparatus for hastening the cooling of soft sugar immediately upon its discharge from the centrifugal machines, which consists of suitable .carrying devices for conducting the sugar as it is discharged from the centrifugal machines into the upper end of a pipe, down which it falls by its own gravity, and into which there is introduced a downwardly-directed blast of cold air, the lower end of said pipe having connected with it a suitable chute, by means of which the sugar falling through the chute by its own gravity and under the inliuence of the blast of air may be thrown at will in different directions or linto different bins, as shown.

2. In combination with apparatus for expe ditiously cooling soft sugar immediately upon its discharge from the. centrifugal machine, substantially such as described, the carrierbelt B, the trough C, the twin screws D d, and the pipe E, the belt-elevator G, and the inclined pipe H, for conducting the sugar into the elevated chamber J, from which it falls by its own gravity through the pipe K.
